From February 8, 1940:
I found this in one of the file cabinets at the transmitter site. It was apparently used as scrap paper because there is what looks like connection information for a remote control system scrawled on the back. I thought it was interesting as it shows a 6 a.m. sign-on and the type of programming, source, and exact times each element ran. For Origins, YN = Yankee Network, BPT = Local Studio (Bridgeport), and NBC = NBC. Program logs for later years (1943) show the Alarm Clock Salute was received via FM from W43B (Paxon, MA) on 49.3 MHz.
Sign-off was at midnight. It must have been cold in that little house out on the island in February.
Anyway, I’ll save these in my radio station history files.
